I am running MySql through wamp and using hibernate and servlet in eclipse. I am getting this error ERROR: HHH000299: Could not complete schema update java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/demo

Servlet.service() for servlet [com.series.controller.TableController] in context with path [/HibernateProject] threw exception org.hibernate.TransactionException: Transaction not successfully started

And the following exception: SAVE: org.hibernate.exception.JDBCConnectionException: Could not open connection

I tried finding suitable driver on google but no luck. Please help
